Tof/.ZZ who/mit may con-cern.

lie it known that I, IVILLIAM E. VHITE, a citizen of the United States,and resident of Chicago, in the county of Cook and State of Illinois,have inventedrgertain new and useful Improvements in an Insert Holder,of which the following is a specification.

My invention relates vto inserts and particularly to a novel deviceintended for use in securing inserts 'to forms prior to the pouring ofconcrete around such inserts. The device here disclosed is animprovement 'upon that shown in my co-pending application, Serial No.445,815, filed Feb. '16, 1921, and is a' 'continuation inpart of mvapplication Serial No. 464,877. y

One of the vobjects of my invention is to provide a device of vthecharacter described, which may be easily applied without the use ofseparate nails and which possesses unusual facility-in the matter ofseparation and removal of the fastening element after the form' has beenstripped.

It is customary in order to secure inserts in proper position to providenotched ears at the sides thereof and to hold the same in place by meansof nails driven into the form. These serve the desired purpose ofsecuring` the insert in 'its position but after the form is stripped,the nails project beyond the face of the concrete and must be cut off ina sub sequent operation. This is an expensive and tedious operation andit is avoided in the construction here disclosed.

In my device I provide a staple which is adapted to interfit with theinsert and to be assembled and shipped, as a part thereof, the pointedends of the staple i'irojecting beyond the bottom face oil the insert.'The arrangement is such that the prongs of the staple may be driveninto a wooden form by a blow applied to the top of the insert. After theform is stripped the staple may be disengaged by a simple operation andin many cases is adapted for reuse if desired. However, the cost thereofis so slight that reuse is not essential` The invention will be morereadily under-` stood by reference to the accompanying drawing, inwhich,

Fig. 1 is a longitudinal sectional view through an insert and fastenerconstructed in accordance with my invention;

Fig. 2 is a transverse sectional View' on. the line 2-2 of Fig. 1; i

Fig. 3 is a bottom plan view, and,

. Fig. ellis a'sectional view onthe `line 4-4 of Figs. 1 and 2. i i iThe insert illustrated herein is the same as that shown in my copendingapplication heretofore referred to. It consists of a box 10, having` ananchor provided ,with a flanged head 11, formed ,as a part thereof. Thebottom wall of the box isconstructed to provide a'lIey-hole slot, thenotched portion 12ot which-is shaped to permit the insertion oftheheadof a bolt while the flanges or lips 13, which surround the narrowportion 14 of the slot serve as supports for said head. The flanges 15which surround the enlarged portion of the opening serve to' support alJ-shaped` keeper 16, mounted for vertical movement ybetween the wallsofl the b'oX. Inoperative position the keeper rests upon the flanges 15and serves as asupport for the bolt-head. p

As a means for securingl the insert in position andffor retaining thekeeper .iny an inoperative positionjprior to the necessity 'for use, Iprovide a staple ywhich consists offan arched vportion 17, and legs :orprongs 18, the ends of which are sharpened. It willbe noted that theflanges 15, `whichv surround the enlarged portion of the slot, are'notched at theirl junction with the flanges v.13, the ,notchesextending inwardly to a point close to theplane of the vside walls. l

These notches receive the, legs 18 of the staple which", when `thestaple isinstalled, are straight as shown` in full, lines in Fig. 2,There is, however, a space 19 between the staple legs and the side walland when a driving force is applied to the portion 11 of the device, inorder to cause the points of the staple to enter a wooden form, theforce is directed against the arched 1nter mediate portion ofthe stapleand if thewood v under ordinary practice, contain a recess orindentation 20 `at the axls of the anchor.y

ceive the legs, 56H95 t0 mly hold" the" sta-ple in position forfthe`driving-r action.

Ubviously the construction is capable of much modiiication and l do notWish'tol bei limited except as indicated in the appended claims. i

l claim:

l. ln an insert,the combination of a housing adapted to be embedded inconcrete and having an internal recess for the accommodation of a boltlead, and a U-shaped tastener yadapted to project into the recess and tointerlock With the housing, said' fastener having pointed ends adaptingit to be driven into a form.

2. lnv a device ot the class described; the combination of a housinghaving a. keyhole slot in its bottom Wall, a movabley keeper adapted tovcov-operate' with the enlarged 'portion of said slot, and a staplea'portion of which is Within and interlocks With said housing andvserves to' retain saidf keeper in' a lixed'position, the endsv of saidstaple projecting-outside oifthe housing and servingas a means forsecuring the housing t0- a form.

3. Ina device ofthe class described, the combination of* housing havingla keyhole slotin its bottom-avail, a movable keeper adapted to(3o-operate with vthe enlarged' por# tion ofsaidsl'ot, and a stapleaportion ot which is Within and'interlocks Withsaid housingan'dserves toretain saidlreeper in an"- inoperativel position, the pointed endsotsaid staple projecting outside ot tlielious'- ing' and'being'adaptedto be driven into a torni, the staple being removable after the form' isstripped, thereby permitting Vthe keeper to assume an operativevposition.

L LLIn an insert, vthe combination o'l a housing adapted to be embedded.in concrete and having an internal'recess for the accommodation of abolt head, a notched flange adjacent to `said-recess, and a staplecooperating with the notch in said flange and iittingwvithin the recessin said head, said staple serving as temporary fastening means for saidhousing 5. ln an insert, the combination of a housing adapted to beembedded.; in concrete and having an iiiterna-lrecess vtor theyaccomi'nodation of a. bolt head, a notched iiange adjacent to saidrecess, and a staple having a if-shaped head tittingwvithin the recess,a leg ot the staple co-operating-With said notch.

G. ln an insert, the combination'oi'la housing having an opening for thereception of a'bolt head, a flange atleach sidey otfsaid opening, theflanges at?X each side being notched'at a point midway oithelengthA -othe housing, andI a staple hai'fing a Vlshaped head tted Withinthe'housinggfl the legs ot the staple occupying notches in saidflanges'.

7. ln an insert, the combinatienof aliousing haaring an openiiigffor`they receptionI of a bolt head, alange' ati eachfsid'e of sa/idopening, the flanges at*y each side being notched, said" notches being1of?v a depth sligh'tlyless than the Width-ofthe-flange, and astaplefitted Withinthehousing land having a headadaptedto"contact'vvitlthe top ivallofthe housing onlyr atapoint midwaybetween the legs, the-flegs'of 'tlfiezfstaple occupying thenotch'e'sin-said flanges, the arrangement beingsuch thatfasa 'drivingforce is appliedto the staplev throughfthe housing the toprof thestaplel is flared?
